WitrynaThe most efficient way of obtaining information about the state of a quantum system is not always a direct measurement. It is sometimes preferable to extend the original Hilbert space of states into a larger space, and then to perform a quantum measurement in the enlarged space. Such an extension is always possible, by virtue of Neumark's … http://scholarpedia.org/article/Neimark-Sacker_bifurcation

Using the proof of Naimark given in [8], the result of Sz.-Nagy is re-derived. It leads to a proof that all products of observables are respected on a suitable subspace of the Naimark resolution.
